Component Reliability
Component Reliability refers to the performance of Line Replaceable Units (LRUs) – such as actuators, radios, computers, valves, instruments, displays, power controls, etc. It is an accepted practice in the industry to define component reliability with a removal rate, such as Mean Time Between Unscheduled Removals (MTBUR), Mean Time Between Failure (MTBF) or Mean Time Between Repairs (MTBR).
Removal rates do not tell you much about the actual performance of a component population. After all, a statistical number does not define a problem. It does not point to root cause. It does not offer a solution. This is why your component reliability program should de-emphasize statistical rates, and instead focus on identifying and resolving common component issues.
